Enantioselective asymmetric michael addition of cyclic diketones to β,γ-unsaturated α-keto esters

An efficient, organocatalytic enantioselective addition of cyclic diketones with β,γ-unsaturated α-keto esters has been developed that affords products in high yields (up to 95%) and excellent enantioselectivity (up to >99ee) under mild conditions with a

Enantioselective synthesis of coumarins catalyzed by a bifunctional amine-thiourea catalyst

Efficient excess: An efficient and facile enantioselective Michael addition reaction through hydrogen-bonding catalysis for the synthesis of coumarin complexes has been developed (see scheme). A simple bifunctional amine-thiourea small molecule has been discovered to catalyze this process with high yields and high to excellent enantiomeric excesses.
